Securing Linux by breaking it with Damn Vulnerable Linux
Damn Vulnerable Linux (DVL) is everything a good Linux distribution isn't.

DVL is a live CD available as a 150MB ISO. It's based on the popular mini-Linux distribution Damn Small Linux (DSL), not only for its minimal size, but also for the fact that DSL uses a 2.4 kernel, which makes it easier to offer vulnerable elements that might not work under the 2.6 kernel.
